Abstract (en)
[origin: EP1223716A2] A waveform generator comprises waveform generating means, for generating a waveform signal using a first band limitation characteristic memory means, for storing in advance the difference between a signal band-limited using the first band limitation characteristic, and a signal band-limited using a second band limitation characteristic; adding means, for adding the signal from the waveform generating means to the difference signal from the memory means, and outputting the signal band-limited using the second band limitation characteristic; and selector switch means, for selectively outputting either the signal from the waveform generating means or the signal from the adding means.
